Abstract

Using data on the external positions of global banks in the world's largest banking hub, the UK, and a granular international-banking model, we show that large banks' idiosyncratic net flows into USD debt influence exchange-rate dynamics. UK-resident banks' USD demand is, on average, price-elastic, whereas their counterparties' USD supply is price-inelastic. We document a structural shift—from banks' being price-inelastic before the Global Financial Crisis to price-elastic afterwards—linked to a marked rise in banks' hedging on-balance-sheet USD net exposures via FX derivatives. This change may help explain the tighter link between exchange rates and macroeconomic fundamentals since the crisis.
